Oxidative addition of (RO)2P(O)H to Pt(0) complexes generating Pt‐H complexes: P(O)‐H bond cleavage vs P(O‐H) bond cleavage

Abstract

(MeO)2P(O)H oxidatively added to Pt(PCy3)2 quickly, at the beginning, generating cis‐Pt‐H[P(O)(OMe)2](PCy3)2 predominately, which gradually isomerized to trans‐Pt‐H[P(O)(OMe)2](PCy3)2. In contrast, a (MeO)2P(OH)‐coordinated Pt complex in situ generated only produced trans‐Pt‐H[P(O)(OMe)2](PCy3)2. These results showed that the P(O)‐H bond perhaps directly adds to Pt(0) complex (P(O)‐H cleavage) forming Pt‐H complexes, rather than by an alternative coordination of (MeO)2P(OH) to Pt(0) followed by an O‐H cleavage path.
